View source for How to visualize multiple sequential breaches (Water Overlay)

When a levee breaks water is free to flow through the breach and onto otherwise dry land. Situations with multiple breaches occurring in rapid succession can be all the more dangerous or impactful.

==Steps==
The use-case can be implemented/completed through the following steps.

|[[How to add and remove an Overlay|Add a Flooding Overlay]].
|Configure the Overlay with a [[Basic water model use case (Water Overlay)|basic hydrological system]].
|[[How to add and remove a Result type|Add a Result type]] of type '[[Surface last value result type (Water Overlay)|Surface last value]]' to the Overlay (if the result type is not present yet).
|Add one or more [[Breach (Water Overlay)|breach]]es to the project. The type of breach will depend on whether the water flows from inside the project area or not in your use case.
|For each breach, [[How to set dynamic breach height|configure a dynamic breach height]].
|Ensure the Overlay is [[Grid_Overlay#Grid recalculation|(re)calculated]].
|Inspect the 'Surface last value' result.
|Select the 'play' option in the Overlay's legend. The animation will show the flow of the water from the breach.
